Over the past couple of years, when Saint Arnold Brewing Company releases a new beer, fans line up hours in advance at places like Spec's and trade tips on Twitter to source a bottle or two of the limited release brew. The company hasn't added a new offering to its year-round lineup in almost two years when it unleashed double IPA Endeavor.

That all changes on Wednesday when Boiler Room Berliner Weisse makes it debut as part of the permanent Saint Arnold family of beers. Brewer Stephen Rawlings created it by accident; during a brewing session for Saint Arnold's classic Lawnmower Ale, half the usual amount of malt ended up on the floor instead of in the mill. Rawlings saved 10 gallons of the "spoiled" batch and added a bottle of high-bacteria Belgian brew to see what would happen.

“This is the most complicated beer we have ever made, yet it is very light and delicate,” said Saint Arnold founder Brock Wagner.

Because of the bacteria that's introduced during brewing, making Boiler Room requires suspending all brewing operations for 48 hours while the bacteria feasts on the wort. In a statement, Rawlings says the Saint Arnold's brewmasters "hacked the brewing system" to prevent the bacteria from spreading and spoiling any of the other beers.

“This is the most complicated beer we have ever made, yet it is very light and delicate,” said Saint Arnold founder Brock Wagner. “The result is an incredibly refreshing beer with the light sweetness of the malt balanced with the tartness from the sour wort. While intended to be enjoyed as is, I can also imagine it mixed with syrups or in a beer cocktail.”

Boiler Room will be available on draft starting Thursday March 20 at craft beer bars like Petrol Station, both the downtown and Sugar Land Flying Saucers, Little Woodrow's in Midtown and The Hay Merchant. Look for it in 22-ounce bombers starting Monday March 24.

Just don't line up for it. Unlike the Boiler Rooms that get raided by the FBI for committing fraud, this one is here to stay.
